🌍 Latitude v1.2.5 — Minecraft 1.21.1

This release brings critical world-generation fixes and long-standing climate correctness improvements to Minecraft 1.21.1, stabilizing Latitude’s behavior across warm and cold zones and resolving several vanilla edge cases.

❄️ Warm-Band Snow Issues — Fixed

Snow appearing in warm climate bands (equator, jungle, tropical regions) has been fully resolved.

What was happening

Vanilla Minecraft could still place snow via internal generation systems (such as top-layer freezing and biome legacy behavior) based on base biomes, even after Latitude reassigned the final biome to a warm climate.

What’s fixed

• Snow blocks no longer generate in warm bands.
• Powder snow (including dangerous cave-mouth sink traps) is blocked in warm climates.
• Snow layers are prevented in warm zones.
• Fix applies reliably to:
  • cave entrances
  • hillsides
  • partially exposed terrain
  • edge-case chunk generation paths

Implementation notes

• Snow placement is intercepted at the final world-generation write stage, ensuring no upstream vanilla logic can bypass Latitude’s climate rules.
• Replacements are handled safely:
  • powder snow / snow layers → AIR
  • snow blocks → DIRT above sea level, STONE below
• Debug logging is disabled by default and available only via explicit JVM flags.

Result: Warm climates now stay warm, without exceptions.

🌴 Mangrove Terrain Improvements

• Fixed incorrect mangrove placement on steep or unsuitable terrain.
• Mangroves now respect terrain suitability and patch logic more consistently.
• Prevents unnatural mangrove growth on hillsides and non-coastal areas.

🧹 Debug & Stability Cleanup

• Reduced verbose biome debug output by default.
• Snow-guard diagnostics and HUD overlays are opt-in only.
• Improves performance and log clarity during normal gameplay.

✅ Summary

Latitude 1.2.5 for Minecraft 1.21.1 delivers:

• Strict enforcement of climate bands
• Removal of rare but immersion-breaking snow anomalies
• More consistent terrain and biome visuals
• A stable foundation for future Latitude updates

This build is intended as a stable release for Minecraft 1.21.1 users.
